I’ve written about declining vehicle miles travelled (VMT) before over at my blog, but this recent post at Communitybuilders.net caught my eye because it disaggregated the data (looking a four states as case studies) between commercial and personal traffic. These data make it seem that commercial trucking (think about frac sand mining or Amazon.com) is […]

Here’s a chart that appears in a (less-than-groundbreaking) discussion about peak vehicle miles traveled, showing average US fuel economy since the 1970s. According to the page (Peak Oil News): The graph also shows that, with the second oil crisis, mileage restarted to increase, but by far not as fast as in the 1970s. There […]
Recently, I wrote about the usage emissions of gas (internal combustion engine), hybrid, and electric vehicles. When we only look at emissions out of the vehicle tailpipe or electric plant smokestack, electric vehicles are clearly the cleaner option for the marginal mile of travel. But as several commenters noted, we really need to look […]
[…] comparison to all other non-drive modes! Take a look at the data for yourself (from the National Household Travel Survey). Total trips are predominantly driving. Of non-personal vehicle modes, that walking is nearly 1/2 is interesting, as is that school buses carry nearly as many people as both cycling and transit. Looking specifically at […]
[…] rural roads. From the document: Further, of the 6,369 fatal crashes involving speeding passenger vehicles, 3,469 occurred on rural roads (55%). According to the FHWA, 920 million vehicle miles traveled (VMT) occurred on rural roads, which represented 30% of the total VMT in 2014 in the United States. Among all of the rural road […]
[…] looking at the wrong place at the wrong time, there’s a higher penalty in terms of distance traveled before you see the problem. But differences in modern vehicle stopping distances at either of those speeds is pretty negligible. Really, the research is pretty clear on what the key difference is between 30 mph and […]
[…] gasoline or hybrid car, take the figure 20.35 pounds of carbon per gallon of gasoline and divide by your fuel economy in miles per gallon. For my vehicle, a 2015 Prius, 20.35 / 45 = 0.452 pounds per mile. To calculate carbon per mile for an electric car, take the FuelEconomy.gov kilowatt-hours per 100 […]
[…] has nothing to do with how much you drive. Here’s the list of policies that might shape this relationship : This indicates that more than half of vehicle costs are either external or internal-fixed. Both external and internal-fixed costs are forms of underpricing that tend to be inefficient and inequitable. For example, parking subsidies […]
